Locktype: posix vs. flock

[Henry Kwan]

Hi,

I've been experimenting with MailScanner and either sendmail or postfix as the
MTA.  I notice that MailScanner uses "flock" locktype with postfix and "posix"
with sendmail.  I also saw in the spam.assassin.prefs.conf file that it said
that "flock", while non-NFS-safe, was more efficient.

Should I tell MailScanner to use "flock" instead of "posix" with sendmail since
I don't have any NFS mounted volumes?

I'm running sendmail-8.13.8-2.

Thanks.
